It's possble, but extremely tricky. Please obtain the DJGPP FAQ
(v2/faq210b.zip from SimTel mirrors) and read chapter 17.5 there. In
fact, the entirety of chapter 17 makes good reading for those trying to
convert 16-bit code to DJGPP.

Not likely. See above.

It is always possible to modify makefiles. However the real problem is
that, if those libraries are not designed with 32-bit flat model
architectures in mind, they almost certainly won't compile even if you
modify the makefiles, and even if you do get them to compile, they
probably won't work without substantial modifications to the code. The
FAQ goes into this in great detail.
It's interesting that you mention Unix in the list of supported
compilers for some of the libraries; if this is in fact the case then it
may not be so difficult to port the libraries to DJGPP. If they support
GCC, then the only code you'll need to modify is anything that tries to
directly interface with hardware, interrupts, etc. Chapter 18 of the
FAQ has a great deal of information on such things.
Hope this helps!
